“…Recalling to the results we got in [15], we have found that the eccentricity can improve the parameters measurement. Unlike the chirp mass and mass ratio, whose improvement by the eccentricity are independent of the total mass of the binary, the source localization improved as the total mass increases.…”

“…When we use the gravitational wave to observe the objects in the Universe, the accuracy of parsing the parameters of the source is important. Interestingly we found in [15] that many parameters can be got more accurately for an eccentric binary than for a quasi-circular binary. Localizing a gravitational wave source is an important issue in gravitational wave detection.…”

“…This EPC model is designed to reproduce the TaylorF2 model at 3.5 PN order in the zero-eccentricity limit and to reproduce the PC model to leading order in the small eccentricity limit. In [15] we have used EPC model to investigate the parameters estimation for an eccentric binary.…”

“…The original EPC waveform involves 11 parameters [15,32], including e 0 , D L , M, η, t c , φ c , ι, β, ψ, θ and φ, where D L is the luminosity distance between the detector and the gravitational-wave source, t c is the arrival time of the coalescence signal respect to the detector, φ c is the orbital phase of coalescence, ψ is the polarization angle respect to the detector, ι and β are the polar angles respect to the detector. θ and φ are the localization spherical angles of the source respect to the detector.…”

Gravitational wave source localization problem is important in gravitational wave astronomy. Regarding ground-based detector, almost all of the previous investigations only considered the difference of arrival time among the detector network for source localization. Within the matched filtering framework, the information beside the arrival time difference can possibly also do some help on source localization. Especially when an eccentric binary is considered, the character involved in the gravitational waveform may improve the source localization. We investigate this effect systematically in the current paper. During the investigation, the enhanced post-circular (EPC) waveform model is used to describe the eccentric binary coalesce. We find that the source localization accuracy does increase along with the eccentricity increases. But such improvement depends on the total mass of the binary. For total mass 100M binary, the source localization accuracy may be improved about 2 times in general when the eccentricity increases from 0 to 0.4. For total mass 65M binary (GW150914-like binary), the improvement factor is about 1.3 when the eccentricity increases from 0 to 0.4. For total mass 22M binary (GW151226-like binary), such improvement is ignorable.
